Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies We prepared our interim condensed consolidated financial statements in conformity with United States of America generally accepted accounting principles, or GAAP, and the reporting regulations of the Securities and Exchange Commission, or the SEC. They do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements include the accounts of SolarWinds Corporation and the accounts of its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions. The interim financial information is unaudited, but reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This interim information should be read in conjunction with the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2019 . Use of Estimates The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts and the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The impact from the rapidly changing market and economic conditions due to the coronavirus disease 2019, or COVID-19, pandemic on our business, results of operations and financial condition is uncertain. We have made estimates of the impact of the COVID-19 pandemic within our financial statements as of and for the three and six months ended June 30, 2020 which did not result in material adjustments. The estimates assessed included, but were not limited to, allowances for credit losses, the carrying values of goodwill and intangible assets and other long-lived assets, valuation allowances for tax assets and revenue recognition and may change in future periods. The actual results that we experience may differ materially from our estimates. The accounting estimates that require our most significant, difficult and subjective judgments include: • the valuation of goodwill, intangibles, long-lived assets and contingent consideration; • revenue recognition; • stock-based compensation; and • income taxes. Recently Adopted Accounting Pronouncements On January 1, 2020 we adopted the Financial Accounting Standards Board, or FASB, Accounting Standards Codification ("ASC") No. 2017-04 "Intangibles-Goodwill and Other," or ASC 350, which simplifies the accounting for goodwill impairment. The new guidance removes step two of the two-step quantitative goodwill impairment test, which requires a hypothetical purchase price allocation. The standard did not have a material impact on our condensed consolidated financial statements for the six months ended June 30, 2020 . Fair Value Measurements We apply the authoritative guidance on fair value measurements for financial assets and liabilities that are measured at fair value on a recurring basis and non-financial assets and liabilities, such as goodwill, intangible assets and property, plant and equipment that are measured at fair value on a non-recurring basis. The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by us. Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1. Level 3: Inputs that are unobservable in the marketplace and significant to the valuation. See Note 4. Fair Value Measurements for a summary of our financial instruments accounted for at fair value on a recurring basis. The carrying amounts reported in our consolidated balance sheets for cash, accounts receivable, accounts payable and other accrued expenses approximate fair value due to relatively short periods to maturity. Accumulated Other Comprehensive Income (Loss) Changes in accumulated other comprehensive income (loss) by component are summarized below: Foreign Currency Translation Adjustments Accumulated Other Comprehensive Income (Loss) (in thousands) Balance at December 31, 2019 $ (5,247 ) $ (5,247 ) Other comprehensive gain (loss) before reclassification (2,651 ) (2,651 ) Amount reclassified from accumulated other comprehensive income (loss) — — Net current period other comprehensive income (loss) (2,651 ) (2,651 ) Balance at June 30, 2020 $ (7,898 ) $ (7,898 ) Deferred Revenue Details of our total deferred revenue balance was as follow s: Total Deferred Revenue (in thousands) Balance at December 31, 2019 $ 343,400 Deferred revenue recognized (245,284 ) Additional amounts deferred 248,303 Balance at June 30, 2020 $ 346,419 We expect to recognize revenue related to remaining performance obligations as follows: Revenue Recognition Expected by Period Total Less than 1 year 1-3 years More than 3 years (in thousands) Expected recognition of deferred revenue $ 346,419 $ 314,105 $ 31,985 $ 329 Deferred Commissions Details of our deferred commissions balance was as follow s: (in thousands) Balance at December 31, 2019 $ 10,624 Commissions capitalized 3,882 Amortization recognized (1,723 ) Balance at June 30, 2020 $ 12,783 June 30, December 31, 2020 2019 Classified as: (in thousands) Current $ 3,159 $ 2,543 Non-current 9,624 8,081 Total deferred commissions $ 12,783 $ 10,624 Cost of Revenue Amortization of Acquired Technologies.

Borrowings under our Revolving Credit Facility bear interest at a floating rate which is, at our option, either (1) a Eurodollar rate for a specified interest period plus an applicable margin of 2.50% or (2) a base rate plus an applicable margin of 1.50% , respectively. The Eurodollar rate applicable to the Revolving Credit Facility is subject to a “floor” of 0.0% . Borrowings under our First Lien Term Loan bear interest at a floating rate which is, at our option, either (1) a Eurodollar rate for a specified interest period plus an applicable margin of 2.75% or (2) a base rate plus an applicable margin of 1.75% , respectively. The Eurodollar rate applicable to the First Lien Term Loan is subject to a “floor” of 0.0% . The Eurodollar rate is equal to an adjusted London Interbank Offered Rate, or LIBOR, for a one -, two -, three - or six -month interest period with a LIBOR floor of 0% . The base rate for any day is a fluctuating rate per annum equal to the highest of (a) the rate of interest in effect for such day as publicly announced by Credit Suisse as its “prime rate” and (b) the federal funds effective rate in effect on such day plus 0.50% and (c) the one-month adjusted LIBOR plus 1.0% per annum. The First Lien Term Loan requires equal quarterly repayments equal to 0.25% of the original principal amount. In addition to paying interest on loans outstanding under the Revolving Credit Facility and the First Lien Term Loan, we are required to pay a commitment fee of 0.50% per annum of unused commitments under the Revolving Credit Facility. The commitment fee is subject to a reduction to 0.375% per annum based on our first lien net leverage ratio. The First Lien Credit Agreement contains a number of covenants that, among other things, restrict, subject to certain exceptions, our ability to: incur additional indebtedness; incur liens; engage in mergers, consolidations, liquidations or dissolutions; pay dividends and distributions on, or redeem, repurchase or retire our capital stock; and make certain investments, acquisitions, loans, or advances. In addition, the terms of the First Lien Credit Agreement include a financial covenant which requires that, at the end of each fiscal quarter, if the aggregate amount of borrowings under the Revolving Credit Facility exceeds 35% of the aggregate commitments under the Revolving Credit Facility, our first lien net leverage ratio cannot exceed 7.40 to 1.00 . The First Lien Credit Agreement also contains certain customary representations and warranties, affirmative covenants and events of default. As of June 30, 2020 , we were in compliance with all covenants of the First Lien Credit Agreement.

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes For the three months ended June 30, 2020 and 2019 , we recorded income tax expense of $4.3 million and $3.2 million , respectively, resulting in an effective tax rate of 25.3% and 297.1% , respectively. For the six months ended June 30, 2020 and 2019 , we recorded income tax expense of $6.8 million and $3.8 million , respectively, resulting in an effective tax rate of 33.8% and 78.6% , respectively. The decrease in the effective tax rate for the three and six months ended June 30, 2020 compared to the same period in 2019 was primarily due to an increase in income before income taxes and the impact of having a full valuation allowance against the deferred tax assets related to the current period losses related to the entities acquired in the SAManage Ltd., or Samanage, acquisition completed in April 2019. Our policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense. At June 30, 2020 , we had accrued interest and penalties related to unrecognized tax benefits of approximately $6.1 million . We file U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2011 through 2018 tax years generally remain open and subject to examination by federal and state tax authorities. The 2011 through 2019 tax years generally remain open and subject to examination by foreign tax authorities. We are currently under examination by the IRS for the tax years 2011 through the period ending February 2016. We are under audit by the Indian Tax Authority for the 2014 and 2017 tax years. We are currently under audit by the California Franchise Tax Board for the 2012 through 2014 tax years and the Massachusetts Department of Revenue for the 2015 through February 2016 tax years. We were notified in February 2020 that the Texas Comptroller would audit the 2015 through 2018 tax years. We are not currently under audit in any other taxing jurisdictions. On July 27, 2015, the U.S. Tax Court issued an opinion in Altera Corp. v. Commissioner related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. In February 2016, the U.S. Internal Revenue Service appealed the decision to the U.S. Court of Appeals for the Ninth Circuit. On June 7, 2019, the Ninth Circuit reversed the 2015 decision of the U.S. Tax Court. On February 10, 2020, Altera Corp. submitted a petition for writ of certiorari to the U.S. Supreme Court. On June 22, 2020, the Supreme Court of the United States denied Altera's petition to review the Ninth Circuit’s decision. Due to the uncertainty surrounding the status of the current regulations, questions related to the scope of potential benefits or obligations, and the risk of the Tax Court's decision being overturned upon appeal, we have not recorded any benefit or expense as of June 30, 2020 . We will continue to monitor ongoing developments and potential impacts to our consolidated financial statements. Governments in certain countries where we do business have enacted legislation in response to the COVID-19 pandemic, including the Coronavirus Aid, Relief, and Economic Security Act, or “CARES Act," enacted by the United States on March 27, 2020. We are continuing to analyze these legislative developments and believe they have not had a material impact on our provision for income taxes for the three and six months ended June 30, 2020 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Legal Proceedings From time to time, we have been and may be involved in various legal proceedings arising in our ordinary course of business. In the opinion of management, resolution of any pending claims (either individually or in the aggregate) is not expected to have a material adverse impact on our consolidated financial statements, cash flows or financial position and it is not possible to provide an estimated amount of any such loss. However, the outcome of disputes is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, an unfavorable resolution of one or more matters could materially affect our future results of operations or cash flows, or both, in a particular period.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Potential Spin-Off of MSP Business On August 6, 2020, the Company announced that its board of directors has authorized management to explore a potential spin-off of its MSP business into a newly created and separately traded public company. If completed, the standalone entity would provide broad and scalable IT service management solutions designed to enable managed service providers, or MSPs, to deliver outsourced IT services for their small and medium size business end-customers and more efficiently manage their own businesses. We would retain our Core IT Management business focused primarily on corporate IT organizations. If we proceed with the spin-off, it would be structured as a tax-free, pro-rata distribution to all Company shareholders as of a record date to be determined by the board of directors of the Company. If completed, upon effectiveness of the transaction, the Company’s shareholders would own shares of both companies. Completion of any spin-off would be subject to various conditions, including final approval of our board of directors, and there can be no assurance that the potential spin-off will be completed in the manner described above, or at all.

Accounting Policies [Abstract]
Basis of Accounting	We prepared our interim condensed consolidated financial statements in conformity with United States of America generally accepted accounting principles, or GAAP, and the reporting regulations of the Securities and Exchange Commission, or the SEC. They do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements include the accounts of SolarWinds Corporation and the accounts of its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions. The interim financial information is unaudited, but reflects all normal adjustments that are, in our opinion, necessary to provide a fair statement of results for the interim periods presented. This interim information should be read in conjunction with the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2019 .
Use of Estimates	The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts and the disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The impact from the rapidly changing market and economic conditions due to the coronavirus disease 2019, or COVID-19, pandemic on our business, results of operations and financial condition is uncertain. We have made estimates of the impact of the COVID-19 pandemic within our financial statements as of and for the three and six months ended June 30, 2020 which did not result in material adjustments. The estimates assessed included, but were not limited to, allowances for credit losses, the carrying values of goodwill and intangible assets and other long-lived assets, valuation allowances for tax assets and revenue recognition and may change in future periods. The actual results that we experience may differ materially from our estimates. The accounting estimates that require our most significant, difficult and subjective judgments include: • the valuation of goodwill, intangibles, long-lived assets and contingent consideration; • revenue recognition; • stock-based compensation; and • income taxes.
Recently Adopted Accounting Pronouncements and Not Yet Adopted	On January 1, 2020 we adopted the Financial Accounting Standards Board, or FASB, Accounting Standards Codification ("ASC") No. 2017-04 "Intangibles-Goodwill and Other," or ASC 350, which simplifies the accounting for goodwill impairment. The new guidance removes step two of the two-step quantitative goodwill impairment test, which requires a hypothetical purchase price allocation. The standard did not have a material impact on our condensed consolidated financial statements for the six months ended June 30, 2020 .
Fair Value Measurements	We apply the authoritative guidance on fair value measurements for financial assets and liabilities that are measured at fair value on a recurring basis and non-financial assets and liabilities, such as goodwill, intangible assets and property, plant and equipment that are measured at fair value on a non-recurring basis. The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by us. Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1. Level 3: Inputs that are unobservable in the marketplace and significant to the valuation. See Note 4. Fair Value Measurements for a summary of our financial instruments accounted for at fair value on a recurring basis. The carrying amounts reported in our consolidated balance sheets for cash, accounts receivable, accounts payable and other accrued expenses approximate fair value due to relatively short periods to maturity.
